[0042] Combination Figures 1 to 6 As shown, this utility model provides a DIO component conversion structure, which includes: a DIO component having a melt discharge end 110; and a single ingot component 20, which includes an adapter 210 and a single ingot sand cup 220. The adapter 210 includes a single ingot dual-channel inlet end 211, a combined flow channel 212, and a single-channel outlet end 213. The dual-channel inlet end is connected to the single-channel outlet end 213 through the combined flow channel 212, and the single-channel outlet end 213 is connected to the single ingot sand cup assembly 220. The dual-ingot assembly 30 includes a dual-ingot dual-channel inlet end 310, a diversion channel 320, and a dual-ingot sand cup 330. The dual-ingot dual-channel inlet end 310 is connected to the dual-ingot sand cup 330 through the diversion channel 320. The DIO assembly conversion structure, depending on the single-ingot mode or the dual-ingot mode, connects the melt outlet end 110 to the single-ingot dual-channel inlet end 211 of the single-ingot assembly 20, or the melt outlet end 110 is connected to the dual-ingot dual-channel inlet end 310 of the dual-ingot assembly 30.

[0043] Specifically, the DIO component is a component used in spinning. In the production of nylon filament, the DIO component is the most important core component in spinning production. It can extrude nylon melt through the DIO component. The DIO component has a melt discharge end 110, which can extrude two strands of melt.

[0044] When two bundles of filaments need to be output, the dual-spindle assembly 30 is connected to the DIO assembly. At this time, the dual-spindle dual-channel inlet end 310 is connected to the melt outlet end 110 to receive the two melts from the DIO assembly. The two melts are diverted to the dual-spindle sand cup 330 through the diversion channel 320 and finally output as two bundles of filaments.

[0045] When a single bundle of filaments needs to be output, the single-spindle assembly 20 is connected to the DIO assembly. At this time, the single-spindle dual-channel inlet end 211 is connected to the melt outlet end 110 to receive the two streams of melt from the DIO assembly. The two streams of melt converge into one after passing through the split channel 320 and the merging channel 212. Then, they flow into the single-spindle sand cup 220 through the single-channel outlet end 213 and finally output a single bundle of filaments.

[0046] Compared with existing technologies, this application allows for the selection of either a single-spindle assembly 20 or a dual-spindle assembly 30 to dock with the DIO assembly, depending on the operating mode. This enables the DIO assembly to output two filament bundles, or to combine the two bundles and output a single high-fineness filament bundle, thus solving the problem of the inability of existing DIO assemblies to combine filaments. This application also allows for rapid switching between the dual-spindle assembly 30 and the single-spindle assembly 20, meeting the production processes with different fineness requirements and providing more process options for spinning production lines.

[0047] In this embodiment, the upper end of the adapter 210 is threadedly connected to the melt discharge end 110, and the lower end of the adapter 210 is threadedly connected to the single-ingot sand cup 220. The single-ingot assembly 20 consists of two parts: the adapter 210 and the single-ingot sand cup 220. The upper end of the adapter 210 has an external thread, and the melt discharge end 110 has an internal thread. The adapter 210 and the DIO assembly are connected by threads to achieve quick disassembly and quick installation. Similarly, the lower end of the adapter 210 has an external thread, and the upper end of the single-ingot sand cup 220 has an internal thread. The adapter 210 and the single-ingot sand cup 220 are connected by threads to achieve quick disassembly and quick installation.

[0048] It should be noted that the adapter 210 and the single-spindle sand cup 220 are two independent components, so that the corresponding adapter 210 can be replaced according to different specifications of DIO components and melt characteristics (the structure of the stranded flow channel 212 of the adapter 210 is adjusted for different specifications) to adapt to different fiber materials.

[0049] In this embodiment, the upper end of the dual-ingot assembly 30 is threadedly connected to the melt discharge end 110. The upper end of the dual-ingot assembly 30 is provided with an external thread, and the melt discharge end 110 is provided with an internal thread. The dual-ingot assembly 30 and the DIO assembly are connected by threads to achieve quick disassembly and quick installation.

[0050] Regarding the structure of the adapter 210, in this embodiment, the single-ingot dual-channel inlet end 211 includes a first single-ingot inlet channel and a second single-ingot inlet channel; the combined flow channel 212 includes a first flow channel and a second flow channel, the inlet of the first flow channel is connected to the first single-ingot inlet channel, the inlet of the second flow channel is connected to the second single-ingot inlet channel, and the outlet of the first flow channel and the outlet of the second flow channel converge and connect to the single-channel outlet end 213. Specifically, after the first single-ingot inlet channel receives one stream of melt from the melt discharge end 110, the melt flows into the first flow channel. Similarly, after the second single-ingot inlet channel receives the other stream of melt from the melt discharge end 110, the melt flows into the second flow channel. The melt in the first flow channel and the melt in the second flow channel finally converge and gradually fuse into one stream, which flows out through the single-channel outlet end 213.

[0051] Furthermore, the first flow channel and the second flow channel are set at an angle to facilitate the convergence and fusion of the two melt streams into a single melt. Moreover, the merging flow channel 212 is designed with optimized fluid dynamics to ensure that the two melt streams gradually merge during flow, avoiding turbulence and dead zones, and guaranteeing uniform merging. Specifically, the distance between the upper end of the first flow channel and the upper end of the second flow channel is a first distance; the distance between the lower end of the first flow channel and the lower end of the second flow channel is a second distance; the first distance is greater than the second distance.

[0052] Furthermore, the merging flow channel 212 also includes guide vanes disposed within the first and second flow channels to guide the two melt streams to converge along an optimal path, reducing flow resistance and ensuring uniform mixing of melts with different viscosities or temperature differences. In other embodiments, the merging flow channel 212 also includes guide grooves.

[0053] Regarding the structure of the dual-spindle assembly 30, in this embodiment, the dual-spindle dual-channel inlet end 310 includes a first dual-spindle inlet channel and a second dual-spindle inlet channel; the diversion channel includes a third channel and a fourth channel, the inlet of the third channel is connected to the first dual-spindle inlet channel, and the inlet of the fourth channel is connected to the second dual-spindle inlet channel; the dual-spindle sand cup 330 includes a first sand cup and a second sand cup, the first sand cup is connected to the outlet of the third channel, and the second sand cup is connected to the outlet of the fourth channel. Specifically, after the first dual-spindle inlet channel receives one stream of melt from the melt outlet end 110, the melt flows into the third channel. Similarly, after the second dual-spindle inlet channel receives the other stream of melt from the melt outlet end 110, the melt flows into the fourth channel; the melt in the third channel and the melt in the fourth channel flow into the first sand cup and the second sand cup, respectively, and finally output two bundles of filaments.

[0054] Furthermore, the distance between the upper end of the third flow channel and the upper end of the fourth flow channel is the third distance; the distance between the upper end of the third flow channel and the lower end of the fourth flow channel is the fourth distance; the third distance is smaller than the fourth distance. Based on the positions of the first and second sand cups, this application reasonably increases the fourth distance, allowing the two streams of melt to flow into the first and second sand cups respectively.

[0055] In one embodiment, the DIO component conversion structure further includes a heater 40 located below the single ingot component 20 to ensure uniform melt temperature during the stranding process and avoid local condensation or poor flow.

[0056] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
